Wei is an engineer for the startup Brief Technology, and was the engineering director at Conshohocken, Pa.-based Monetate for nearly two years, where she led a team of seven engineers. Before becoming a developer, she was projectmanager, but yearned to create.

"[Web development] wasn’t something I knew I wanted to do until I worked alongside developers in an agency setting and I said, 'I want to make things,'" Wei told Philadelphia Business Journal.

Wei, who had already been teaching classes at Girl Develop It for about three years, joins Yasmine Mustafa as the Philadelphia chapter's co-leader.

She said she hopes to increase the ratio of women in the developer community in Philadelphia from 30 percent women to 50 percent.

Girl Develop It offers classes in fields like HTML/CSS, Javascript, PHL/MYSQL and more.
